I'm getting ready to install a new 4500 converter to take the place of my current 4000. I plan on making a few test pass afterwards to see if I pickup anything. I was wondering if installing a set of 4.88 gears and a pair of 30x9x15 Hoosier radial slicks would pick me up over my current 4.11/ 27x11.5x15 QTP's. I don't have any problem hooking now, but everybody keeps telling me that the 4.88/30in tire combo will make a difference and I don't now what to do.

you may run into a clearance problem. I am running Hoosier 29x10x15 and I still had to cut from the plastic and roll the wheel wells. I am also running a 4.88 gear and have thought about getting the 30's under there as I have seen many stockers running a taller tire with either 4.88 or 5.13 gears

I test fitted a pair of my buddies 30in tires and I think all I would have to do is trim the bumper cover alittle more. I would love the 4.88/30in combo on the car, but only if I can see a gain in performance. I'll have to get in touch with some of my friends that run stock eliminator and H/crate motor and see what they say, if I didn't already know.

It would probably help as long as you turn your engine up to 6800-7000. I don't know why but my car always ran well with high gears. I went from 3.42's/26" tires and the car ran 120mph in the 1/4. Then I put some 28" Drag Radials, same gears and fiquered the car would slow down a bunch but it still ran 11.40@119mph in worse weather conditions. I will try running a little more gear (3.73's) with my new setup next month or so. Later Clint

Well I guess I'm going to do it. I order the gears,tires, and a new set of wheels, and I'll let everybody know what it does as soon as I get it to the track.

Hey Randy,
Just give it the ol' college try and see what happens. If you don't like it, you can always go back to your old set up. Keep us posted.

Hey Mac! It's good hear from you. I've got everything installed yesterday and now just have to wait to get to the track. I was amazed at how easy it was to fit the 30in tires, all I had to do was cut about 2in off of the bumper cover and fender. The tire has at least 3/4 of an inch at it's closest point, and the guys that I know that run these radials say that they don't grow so I should be in good shape. I keep everyone posted after I get to the track.
